SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No, 307,165, dated October28, 1884.

Application filed March 15, 1883. (No model.)

To all whom it may concern:

Be it known that I, AMMI B. BENJAMIN, a citizen of the United States ofAmerica, residing at Kelloggsville, in the county of Ashtabula and Stateof Ohio, have invented certain new and useful Improvements in Spark-Arresters; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to that class of sparkarresters in which a bodyof water is arranged to catch the sparks, which are carried into it bysuitable deflectors of the draft.

The object of my invention is to simplify the construction of this classof spark-arresters and render them more efficient and reliable thanheretofore; and with these objects in View my improvement consists incertain novel constructions and combinations of parts, which will behereinafter particularly described, and pointed out in the appendedclaim. I

In the accompanying drawing the figure is a vertical section of asmoke-stack and sparkarrester constructed according to my invention.

My spark-arrester is intended especially for use in connection with farmor road engines and the like, but may of course be used in connectionwith any apparatus to which such a device is applicable.

In the drawing, D designates the upper part or head of the smoke-stack,under which is the cylindrical portion D, hinged to thesmokebox in theusual manner, and connected with the flaring or funnel-shaped portion D,a curved angular deflector or flange, I, surrounding the head andsupporting the central tube, J, which extends slightly into the head afew inches, has its lower end projecting below the same. Within theflaring portion D of the stack is centrally arranged a reservoir, E, thelower portion of which has the form of an inverted cone, while its up-"per portion is cylindrical-and surrounds the lower end of the pipe J,being separated therefrom by an intervening space, which is about equalin width to that of the space between all parts of the reservoir and thesmokestack, this space forming an annular flue, A.

L indicatesthe exhaust-pipe, which terminates in the smoke-stackdirectly under the pointed lower end of the reservoir.

G is a supplyepipe through which water may be furnished to thereservoir, and H is an overflow-pipe by which the water in the reservoiris prevented from rising higher than a proper level. The inner rim orflange, M, on the upper edge of the reservoir prevents the water fromsplashing over intothe flue A.

The operation of the apparatus is as follows: The blast from theexhaust-pipeL drives the smoke and sparks forcibly upward throughthe'flue A, surrounding the reservoir E, and the sparks striking thedeflector I are carried against the pipe J and into the water WV, whilethe smoke rises and passes off through the pipe J. The upper portion ofthe stack, which carries the flange I andpipe J, is connected by aslip-joint at d to the lower portion, so that it may be readily removedtherefrom to permit the reservoir to be inserted or removed, saidreservoir being held in place by suitable braces, as shown.

I am aware that smoke-stacks have been provided with annular reservoirsthrough the center of which the draft passes and is deflected thereintoby suitable deflecting-plates, and I lay no claim to such construction.

What I claim is- The combination, in a spark-arrester, of a smoke-stack,D, having the cylindrical portion D, flaring portion D and inward anddownward bent flange I, of the smoke-pipe J. secured to said flange andwithin the central opening surrounded by the same and projecting belowsaid flange, and of the-conical reservoir E, removably arranged withinthe smokestack and provided with a rim, M, and having its open upper endterminating under said flange and surrounding the lower portion of thepipe J, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

AMMI B. BENJAMIN.
